A low percentage means the fabric performs well at reducing solar energy. Solar reflectance: Rs this factor gives the proportion of solar radiation reflected by the fabric. A high percentage means the fabric performs well at reflecting solar energy. Solar absorptance: As this factor gives the proportion of solar radiation absorbed by the fabric. A low percentage means the fabric absorbs little solar energy. Solar radiation is always partially transmitted through, absorbed or reflected by the fabric. The sum of all 3 equals 100. Ts + Rs + As = 100 % of solar energy.

Sunscreen <strong>Natté</strong><strong>4503</strong> ® Thermal factors calculation using reference glazing and according to the position of the blind (indoor or outdoor) Shading coefficient Sc (or Fc shading factor or z*): this factor shows how effective the fabric is at filtering the heat from solar radiation. It is expressed as a factor between 0 and 1. A low figure means high protection from heat flow. Solar factor or gtot Fs factor*: the percentage of solar energy which actually penetrates into a room through the blind and glazing. Fs = Sc x Fs of glazing or in European terminology: gtot = Fc x g of glazing* The solar factor of the glazing (Fs of glazing or g of glazing) is an indication given by plain glass manufacturers. This is often given randomly as g of glazing = 0.75 as reference for standard double glazing. > Optical factors Visible transmittance Tv (or TL Light transmission): this factor gives the total percentage of light radiated through the fabric over a wavelength of 380 to 780nm (nanometers), called the visible spectrum (total illumination). Openness factor Of (or Co Openness coefficient*): this factor gives, in brief, a percentage of holes in a fabric. In the European standard, it is considered as independent of the colour but, for fabrics with the same weave, it should be measured using the darkest colour in the range. Diffuse transmission Tdif factor*: correlation of the two factors above: Tdif = Tv – Co The diffuse part of total light transmission is indicated as Tvdif for the aspects of glare and shape recognition (visual contact to the outside/night privacy). However, for natural light control, it is indicated as Tvdifh. This is used to ascertain a fabric’s light diffusion capacity. Panel becomes a source of light if the sun shines directly on it. The light intensity, or "luminance", emitted by a fabric can also be measured in candelas/m 2 (Cd/m 2 ). Ultraviolet Tuv transmittance factor: this factor gives the percentage of ultraviolet light radiated through the fabric over a wavelength of 280 to 380 nm (nanometers). UV radiation accelerates natural ageing. All means of solar protection ensure a certain amount of protection from UV rays. * European terminology > Exterior > Interior Dark colour Charcoal 3030 Light colour White 0202 Visual transmission (Tv or TL) Tv = 4 % Tv = 15 % Thermal transmission Total solar factor (gtot or fs) gtot = 9 % gtot = 13 % Dark colour Charcoal 3030 Light colour White 0202 Visual transmission (Tv or TL) Tv = 4 % Tv = 15 % Thermal transmission Total solar factor (gtot or fs) gtot = 37 % gtot = 25 % > www.sunscreen-mermet.com
